BURNER.

Application filed April 6, 1925. lSeria1`No. 21,117.

My invention relates to fuel burners, and ,is more particularly designed as an improvement on a burner forming the subject matter of an application tiled by me June 22, 192e, Serial. No. 647,113.

The object. of the present invention is to provide a new assemblage for the burner proper, includinga novel butt ring on and adjacent to which the combustion takes place, as well as to provide elements associated with the butt 'ring and co-acting therewith to bring about effective combustion as well as preheating of the butt ring and adjacent parts.

The nature of my invention and its -distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming` part of this specification, it beingunderstood that the drawings are merely illustrative of one example of the invention.

Figure l is a vertical section of the burner embodying my present invention.

Figure 2 is' a fragmentary view in vertical sectionv indicating the course of the air and oil land the location of the main area of combustion.

Figure 3 is a plan view of the outer guard ring with the refractory collar omitted, said ring and said collar being hereinafter further referred to.

-Figure I4 is a plan view of the butt ring on which combustion takes place, and

Figure l5 is a plan view of the inner guard ring within the buttring. u In carrying out my invention in accordance with the illustrated example, a cyclone air box 10 is provided, as n'my application above referred to, as well as a drip pan 11 supported on the upper edge of said The numeral 12 indicates a nozzle plied by an oil pipe 14. '1 he numeral 15 indicates a drip pipe formlng no part of the present invention, and 16 a gas inlet pipe for the preheating gas burner' ring 17. Disposed in theA nozzle 12 1s a' vertical spindle 18 projecting above the top of said nozzle and provided with a spreader fan 19, peripheral blades 20 of which are disposed above an air spreader head 21 secured to the upper. end of the nozzle 12. A collar 22 is positioned about the nozzle 12and secured thereto by arms 23 and 24. Said collar 22 has a vertical annular fla-nge or neck 25 thereon.` The elements thus far described are disclosed in my aforenamed application and are disclaimed Vherein except as they co-act with the butt ring 26, the outer guard ring 27 having refractory material 28, and the linner guard ring 29 which is disposed about the neck or flange 25.

The outer guard ring 27 rests on the upper edge of 'a vertical iiange 111 on the drip pan llvoutside of the butt ring 26 and has a specific construction hereinafter further explained. The butt ring 26 has depending members 126 resting on the outer guard ring 27 and is spaced from the refractory lining 28 of said guard ring. The members 126 sustain the butt ring 26 raised from the general surface of the ring 27, the arrangement being such that gas from the preheating pipe 17 will pass beneath the butt ring 26 to the surface of the refractory lining 28. Preheating gas `from thepipe 17 passesalso between the butt ring 26 and the .inner guard ring 29, for which purpose said Eguard ring has cut-outs 30 formed therein, and similar cut-outs 31 are produced in the inner edge of the butt ring 26, so that gas may rise through -said cut-outs,

hence in preheating of the butt .ring 26 and the surfaces adjacent thereto, the gas from the pipe 17 will pass upwardly within the ringr 26 and outside of the same so the said ring and the adjacent surfaces are thoroughly heated as the gas from the ring 17 is burned. The outer guard ring 27 has radial ribs 32 or equivalent projecting elements which interengage with the refractory lining 28 and prevent displacement of the latter. The ring 27 also has concave depressions 33 at the inner edge thereof, through which the gas from pipe 17 passes to the space between the butt ring 26 and the lining 28. On the upper side of the outer guard ring 27, the same is formed with an' annular lip 127 at the inner edge to prevent any oil from dripping into the box 10. i

-The butt rng.26 is formed withan inner annular bead 34 and an outer annular bead 35 rising higher than the bead 34, thereby forming anannular depression 36 which serves to retain atomized fluid fuel until the same is consumed. The Huid fuel is received by pipe 14, chamber 13 and nozzle 12 and passes through 4nozzle 12 and through the spreader head 21 vto lthe upper side of the latter beneath the fan 19. At the same time, air rises through ythe box 1() and passes out. beneath the spreader head 32, thereby assing the fan blades 20 and causing the fan to rotate for directing atomized fuel to thedepression 36 of butt ringv 26.

The inner guard ring 29 rests on screws 37 in suitable number on the collar 22, one of said screws showing in Figure 1.. By adjusting the screws 37, the inner guard ring 29 is raised or lowered to adjust it relatively' to the butt ring 26. Guard ring 29 roteets gas ring 17 from the heat of the ame. l

The numeral 40 indicates frame spreader elements. It will be observed the spreader elements 10 a're of ovate form and are placed at intervals about the burner radially outward of the flame passage beneath the ring 26.'

The .outer bead 35, in addition to functioning to retain the fuel in the channel 3G, serves also as an air guard to prevent external air from commingling with the fuel during combustion, which would result in a deposit of carbon. By provision of the guard bead or flange 35, the air supply to the burning fuel is practically confined to that air passing through box 10 and beneath head 32 'and fan blades 20. As explained in my previous application, oil passes from the drip pan 11 out at spout 38 and drops to the bottom of the box 10,

Where it escapes by the drip pipe 15, but these features form no part of the invention claimed in the present application.

.I would state in conclusion that while the illustrated example constitutes /a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since, manifestly, the same can be considerably varied without departure from'the spirit of the invention as defined -in the appended claims.

Having thus described my invention, I claim;

1. In a burner, a butt ring adapted to receive uid fuel to be burned, an outer `guard ring extending at its outer portion above the butt ring and extending at its inner portion beneath saidbutt ring, said butt ring being spaced from the guard ring, and means lwithin said butt ring adapted to direct fluid fuel thereto; together with an inner guard ring within and below the butt ring, there being openings between the butt ring and .the inner guard rnghand a gasA supply disposed beneath said inner guard ring whereby to direct gas to the inside and outside of said butt ring.

2. In a burner, an annular element having a depressed portion adapted to hold fluid fuel, a guard ring having a portion extending beneath the said element and a portion outward of and rising above said element, and means to direct gas beneath said element between said element and said guard ring.

3. In a burner, an annular element adapted to receive fluid fuel, and a guard ring outside of said annular element and rising above the same, together with ovate guard 'elements disposed at intervals between said annular element and said ring.

4. In a burner, an annular element adapted to hold fuel to be burned, a guard 'ring at the inside of said element havingr a portion extending beneath the same, and screws sustaining said guard ring and adapted to adjust the same vertically.

5; In a burner, an annularv element adapted to receive fluid fuel, a guard ring having a portion spaced from and laterally outward of said element and rising above the same, said guard ring extending beneath and spaced from the bottom of said element, a refractory facing on said guard ring, andmembers on the guard ring engaging with said refractory facing to prevent displacement thereof.

6. In a burner, an annular element adapted to receive fuel to be burned, a guard ring outside of and spaced from said element, means to direct fuel beneath said eilement between said element and said ring, and ovate guard elements disposed at intervals between said inner element and said ring in position to spread the flame from the fuel supplied to said space. 7. In a burner, a fuel supply pipe, an inner guard ring adjacent said fuel supply pipe and extending about the same, a second fuel supply pipe beneath said inner guard ring for pre-heating the burner parts, a butt ring outside of said inner guard ring and an outer guard ring outside of said butt ring, said butt ring and said inner guard ring having vertical registering openings and said fuel supply pipe having a discharge orifice beneath said openings whereby fuel will pass from said second-memtioned fuel supply pipe upwardly through said openings in said inner guard ring and said butt ring.
